Maximum Lift Reference Table
The following is a chart that can be used to determine your projected maximum without performing a 1 repetition max. Some athletes "get psyched" for a maximum lift, while others
get psyched out by the number 300,350, or 400. But as a rule, the chart gives a good indication of what an athlete is capable of for a single lift.

Example: The first column all the way to the left is the weight that you are using. So let's say you use 135 lbs. If you can bench 135 lbs for 8 reps than your estimated one rep max is 167 lbs.
So just slide your finger across the page and line it up with the number of times you can lift the weight. Yes you can use this chart for other lifts such as the squat as well.
